Custom Tensor Processing Unit chip revealed as secret to Google's AI capabilities – Tech2

Google has designed and deployed a custom chip for driving its machine learning technologies. The chips are custom made to work with TensorFlow, Google's machine learning platform. The technology was stealthily developed, and is already deployed for Street View, Inbox Smart Reply and RankBrain, which is the brains behind delivering more relevant search results. The chips are named Tensor Processing Units (TPU). It delivers better performance optimisation per unit of electricity consumption, an order of magnitude better than any other product in the market.
